Problem

glew32s.lib is not linking correctly with the main executable. When building with MakeFile given by CMake, an error occurs stating that I have an undefined reference to glewInit().

CMakeFiles\NoGameEngine.dir/objects.a(window.cpp.obj):window.cpp:(.text+0x15d): undefined reference to `glewInit'

However in my top-level CMakeLists.txt I have linked the glew32s.lib through:

target_link_libraries( ${PROJECT_NAME} PRIVATE ${CMAKE_SOURCE_DIR}/Dependencies/glew32s.lib)

I am completely clueless to why I am getting this undefined reference error. Note I have also declared the compile option -DGLEW_STATIC.

What I have tried

Using another way to link the library:

target_link_directories( ${PROJECT_NAME} PRIVATE Dependencies)
target_link_libraries( ${PROJECT_NAME} PRIVATE glew32s.lib)

However I get the following errors:

C:/MinGW64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: skipping incompatible C:/PROGRA~4/C__~1/Projects/GAMEPR~1/NOGAME~1/DEPEND~1/glew32s.lib when searching for -lglew32s C:/MinGW64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: skipping incompatible C:/PROGRA~4/C__~1/Projects/GAMEPR~1/NOGAME~1/DEPEND~1/glew32s.lib when searching for -lglew32s C:/MinGW64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: skipping incompatible C:/PROGRA~4/C__~1/Projects/GAMEPR~1/NOGAME~1/DEPEND~1\glew32s.lib when searching for -lglew32s C:/MinGW64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lglew32s
