cmake options confusion

[quetzalsly]

#set(GLM_ENABLE_CXX_17 ON CACHE BOOL "" FORCE)
#set(GLM_ENABLE_CXX_20 OFF CACHE BOOL "" FORCE)
#set(GLM_ENABLE_LANG_EXTENSIONS ON CACHE BOOL "" FORCE)
#set(GLM_ENABLE_SIMD_SSE2 ON CACHE BOOL "" FORCE)
#set(GLM_ENABLE_SIMD_SSE3 ON CACHE BOOL "" FORCE)
#set(GLM_ENABLE_SIMD_SSSE3 ON CACHE BOOL "" FORCE)
#set(GLM_ENABLE_SIMD_SSE4_1 ON CACHE BOOL "" FORCE)
#set(GLM_ENABLE_SIMD_SSE4_2 ON CACHE BOOL "" FORCE)
#set(GLM_ENABLE_SIMD_AVX ON CACHE BOOL "" FORCE)
#set(GLM_ENABLE_SIMD_AVX2 ON CACHE BOOL "" FORCE)
#set(GLM_ENABLE_SIMD_NEON ON CACHE BOOL "" FORCE)

Are we supposed to set these manually? they are unticked for me after configuring unless I manually set them.
However some of these options cause my build to fail with a linker error something like cant find glm.lib
If I dont set any options then it builds and runs fine.
