Unable to generate executable file using compiler - c++

I am trying to compile my source code using riscv64-unknown-elf-g++ compiler into a binary file but I am getting this warning and unable to generate exec file:
warning for library: libofdm.a the table of contents is empty (no object file members in the library define global symbols)
referring to this issue before:
Can't make my c++ file into a library with compiler
as suggested in the above answer the same toolchain is used to compile the object file to create the library. Even though I am getting the error. Below I am attaching the whole command line used to compile.

CMake cannot generate protocolbuf headers and source files on Windows

I am trying to compile a .proto file on Windows using CMake (version 3.23.1). To this aim, I am using documentations that can be found here and here. But at the end, the .cc and .h files are not generated. Here is my CMakeLists.txt file:

I am getting this output:

How to compile RealSense examples?

I have cloned the RealSense official source code from their Github page. There was a problem when I was compiling the example align-advanced. The following is my terminal situation:
$ cd ~/librealsense/examples/align-advanced
$ mkdir build
$ cd build
~/librealsense/examples/align-advanced/build$ cmake ..

As you can see, nothing happens after typing make, and no executable files appear in the build folder.

endif()
What is the problem?
CMake was intended to be run from the top-level directory of the entire project. This is a general CMake rule-of-thumb; it typically applies to any CMake-based project, not only RealSense.
If you want to enable the compilation of the RealSense examples, you can control it via CMake with the BUILD_EXAMPLES variable, as seen the Build Configuration documentation. This only builds a small subset of the examples, however. To build the align-advanced examples, you also need to set BUILD_GRAPHICAL_EXAMPLES:
cd ~/librealsense
mkdir build; cd build
cmake -DBUILD_EXAMPLES=true -DBUILD_GRAPHICAL_EXAMPLES=true ..
make

CMake WxWidgets project successfully built on linux but not on windows

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).

Distribute a Qt5 console application using CMake

I fruitlessly tried to distribute a basic Qt console application by using CMake.
Let's consider these 2 files:
main.cpp
#include <QDebug>
int main(int argc, char *argv[])
{
qDebug() << "Hello Wolrd!";
return 0;
}
CMakeLists.txt
cmake_minimum_required(VERSION 2.8.12)
project(HelloWorld)
set(CMAKE_AUTOMOC ON)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
find_package(Qt5Widgets REQUIRED)
add_executable(${PROJECT_NAME} main.cpp)
qt5_use_modules(${PROJECT_NAME} Widgets)
Next I compile the main.cpp file doing:
$ cmake .
-- The C compiler identification is AppleClang 10.0.1.10010046
-- The CXX compiler identification is AppleClang 10.0.1.10010046

And I get a HelloWorld binary file.
The problem comes when I try to execute the latter file on another computer which don't have Qt installed. I get this bellow error:

Reason: image not found

What is missing to make this working as a standalone application?
Environment:
MacOs Mojave (10.14.4)
Qt 5.10.1
The easiest approach is to link Qt statically. Check out the documentation about deploying for macOS.
Be aware that Qt is licensed under the LGPL, which may have implications for static linking. Check out this FAQ for details.
You could also use bundles and frameworks, but I'm not sure how well that works with console applications.
