Using Ubuntu LTS 14.04.
Trying to set up codelite to develop in c++ following this tutorial TheChernoProject How to Setup C++ on Linux
CMakeLists.txt:
cmake_minimum_required (VERSION 3.5)
project (HelloWorld)
set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Werror -std=c++14")
set (source_dir "${PROJECT_SOURCE_DIR}/src/")
file (GLOB source_files "${source_dir}/*.cpp")
add_executable (HelloWorld ${source_files})
build.sh:
#!/bin/sh
cmake -G "CodeLite - Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug
EDIT:
After consulting the Documentation https://github.com/eranif/codelite I modified build.sh to:
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug
and it worked. and gave the output:
-- The C compiler identification is GNU 4.8.4
-- The CXX compiler identification is GNU 4.8.4
-- Check for working C compiler: /usr/bin/cc
-- Check for working C compiler: /usr/bin/cc -- works

-- Check for working CXX compiler: /usr/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Configuring done
-- Generating done
However the HelloWorld workspace was not generated
I created a fresh project from scratch purely using CodeLite and it generated the CMake file for me. Everything worked flawlessly.

I dont know how to change the compiler to G++
this is the cmake
cmake_minimum_required(VERSION 3.0)
set(CMAKE_C_COMPILER "gcc")
set(CMAKE_CXX_COMPILER "g++")
project(HelLo)
add_executable(Hello main.cpp hello.cpp)
I am on windows , Thanks for help
(I can compile with g++ and gcc just cmakefile dont work )
First, make sure you've installed gcc/g++ under Windows (either CygWin or MinGW). Remove the set commands from your CMakelists.txt. Then in a CygWin/MinGW shell use the following command to generate the Makefile:
CC=gcc CXX=c++ cmake ..
cmake -G "Unix Makefiles" ..
When using this CMakeLists.txt
cmake_minimum_required(VERSION 3.17)
project(project_c)
set(CMAKE_CXX_STANDARD 11)
set(project_name project_c)
find_package(BISON)
find_package(FLEX)
BISON_TARGET(parser parser.y ${CMAKE_SOURCE_DIR}/parser.cpp)
FLEX_TARGET(lexer lexer.l ${CMAKE_SOURCE_DIR}/lexer.cpp)
ADD_FLEX_BISON_DEPENDENCY(lexer parser)
add_executable(${project_name} ${BISON_parser_OUTPUTS} ${FLEX_lexer_OUTPUTS})
target_include_directories(${project_name} PRIVATE "${CMAKE_CURRENT_BINARY_DIR}")
target_link_libraries(${project_name} ${FLEX_LIBRARIES})
CMake complains about
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

I've tried to copy the winflex folder inside the project folder but that won't help anyway. This proposed solution isn't working.

I've managed to build a WxWidgets based on CMake on Ubuntu 19.10, but failed on Windows 10, saying that it cannot find WxWidgets, though I've built it successfully (static, release and with unicode support).
WxWidgets path is C:\wxWidgets-3.1.3 and the build directory is C:\wxWidgets-3.1.3\msw-release.
The makefile is
cmake_minimum_required(VERSION 3.0)
project(ChessPgnReviser VERSION 0.1.0)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
ADD_DEFINITIONS(-Wall -Wno-sign-compare -O2)
set(SRCS
src/main.cpp
)
set (HEADERS
)
message( "--Root--" ${wxWidgets_ROOT_DIR} )
message( "--Lib dir--" ${wxWidgets_LIB_DIR} )
add_executable(ChessPgnReviser ${SRCS} ${HEADERS})
find_package(wxWidgets COMPONENTS net gl core base)
if(wxWidgets_FOUND)
include(${wxWidgets_USE_FILE})
target_link_libraries(ChessPgnReviser ${wxWidgets_LIBRARIES})
else()
message(FATAL_ERROR "Failed to find WxWidgets library")
endif()
I'm using Msys 64 bit in order to compile the project. At the bottom of its subfolder etc/profile, I've added
PATH=$PATH:/c/dev/cmake/bin
wxWidgets_ROOT_DIR=/c/wxWidgets-3.1.3
wxWidgets_LIBRARIES=$wxWidgets_ROOT_DIR/msw-release/lib
wxWidgets_LIB_DIR=$wxWidgets_ROOT_DIR/msw-release/lib
wxWidgets_INCLUDE_DIRS=$wxWidgets_ROOT_DIR/include
So I've tried
$ mkdir build && cd build
$ cmake .. -G "MinGW Makefiles"

Also, thanks to #squareskittles, I also tried:

You can find the content of the msw-release folder : there.
Also:
$ ls /c/wxWidgets-3.1.3/msw-release/lib/
libwx_baseu_net-3.1.a libwx_baseu-3.1.a libwx_mswu_aui-3.1.a libwx_mswu_gl-3.1.a libwx_mswu_media-3.1.a libwx_mswu_qa-3.1.a libwx_mswu_richtext-3.1.a libwx_mswu_webview-3.1.a libwxregexu-3.1.a wx
libwx_baseu_xml-3.1.a libwx_mswu_adv-3.1.a libwx_mswu_core-3.1.a libwx_mswu_html-3.1.a libwx_mswu_propgrid-3.1.a libwx_mswu_ribbon-3.1.a libwx_mswu_stc-3.1.a libwx_mswu_xrc-3.1.a libwxscintilla-3.1.a
So did I forget something ?
To properly detect wxWidgets you need wx-config.
A Windows version of wx-config exists and can be downloaded from: https://github.com/kowey/wx-config-win
To make wx-config know where your wxWidgets is, you need set the following environment variables:
WXWIN (in your case to C:/wxWidgets-3.1.3)
WXCFG (in your case to something like msw/gcc_mswu).
I run CMake using cmake .. in order to make it output all the generated files in a different directory. This runs fine on Ubuntu, but breaks on Windows 10 when I try to run it. Running cmake . from the root project directory seems to work fine on both platforms. The output of cmake .. on Windows is:
PS D:\Development\cpp\hello-vulkan\build> cmake ..

The CMakeLists.txt is specified here:

set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/build/)
set(SOURCES source/main.cpp)
add_executable(hello_vulkan ${SOURCES})
add_dependencies(hello_vulkan glfw)
Any ideas what to do for it to work when running from a different directory on Windows?

So, i set up my Cloin/SFML project like this : configure SFML for clion (windows)
and added the SFML_ROOT variable, and then it works exactly once, and every time i try too run it after the first, i get this error(gam is the project name, it is set correctly in the CMakeLists.txt file):
mingw32-make.exe: *** No rule to make target 'gam'. Stop.
How do i get it to work more than once?(It might be something as stupid as me clicking the wrong button to run this thing. I´m new to Clion and cmake)
CMakeLists.txt:
cmake_minimum_required(VERSION 3.12)
project(gam)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp)
add_executable(gam ${SOURCE_FILES})
set(CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/cmake_modules")
find_package(SFML REQUIRED system window graphics network audio)
if (SFML_FOUND)
include_directories(${SFML_INCLUDE_DIR})
target_link_libraries(gam ${SFML_LIBRARIES})
endif()
