While running cmake 3.21.1 (shipped with Qt online installer) on same project on macOS and Windows I get different output. Why? And how to make it more verbose on Windows?

I want to link openssl library statically in my C++ shared library project because I want to distribute my shared library in a single dll file.
So I added the following codes in my CMakeLists.txt:
set(OPENSSL_USE_STATIC_LIBS TRUE)
find_package(OpenSSL REQUIRED)
target_link_libraries(std OpenSSL::SSL OpenSSL::Crypto)
And here are the logs of cmake:

However, the shared library couldn't be loaded. I checked its behavior with ProcessMonitor. The library tried to load libcrypto-1_1-x64.dll and libssl-1_1-x64.dll but failed. How can I solve it?
I am new in c++

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" ..
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'm trying to use the KPlotting widget with a Qt (v5.14) project that uses CMake (v3.10.2).
I installed the KDE Extra CMake Modules by cloning the repo, then running: cmake, make, sudo make install.
I added find_package(KF5Plotting) to my top-level CMakeLists.txt file, and target_link_libraries(${PROJECT_NAME} KF5::Plotting) in the CMakeLists.txt file in my src directory. However, when I compile I get the following error:
ui_mainwindow.h:30:10: fatal error: kplotwidget.h: No such file or directory
#include <kplotwidget.h>
This seems to indicate that the call to find_package didn't work, but I'm unsure how to check. Am I simply missing an include directory directive in CMake? Any help on how to get this to compile would be greatly appreciated!
UPDATE:
If I add REQUIRED to find_package, nothing seems to change, and the output is simply:

Also, I installed KPlotting via apt (libkf5plotting-dev & libkf5plotting5) on Ubuntu 18.04
I have a very simple "Hello world" program that compiles with mpic++. I also have the following CMakeLists.txt file:
