CMake Compiler not set-CodePudding

CMake Error: CMAKE_Project_COMPILER not set, after EnableLanguage

I Get this Error after writing cmake ..

This is my CMakeLists.txt


set(CMAKE_CXX_COMPILER "C:/mingw64/bin/g  ")
set(CMAKE_C_COMPILER "C:/mingw64/bin/gcc")

project(CXX Project)

add_subdirectory(glfw/)

add_executable(${PROJECT_NAME} Main.cpp)
target_include_directories(${PROJECT_NAME} PUBLIC glfw)
target_link_libraries(${PROJECT_NAME} PUBLIC glfw)```

CodePudding user response：

You're using the project command in the wrong way. It should be

project(Project CXX)

That's why CMake is looking for CMAKE_Project_COMPILER instead of CMAKE_CXX_COMPILER.

CodePudding user response：

As you can see in your error message cmake is trying to generate build files for nmake, the visual studio build system. What you are trying to setup is a makefile based build system with mingw. Therefore you should specify the generator directly:

cmake .. -G "MinGW Makefiles"
