glm_FOUND should be GLM_FOUND

[themightyoarfish]

Similar to my other issues, this applies to macos. I have glm from homebrew (1.0.1) and after

find_package(glm)

The variable glm_FOUND is empty, but GLM_FOUND is TRUE. Thus the logic of downloading glm inside the build tree triggers unintentionally. The vendored FindGLM.cmake uses uppercase, the homebrew module uses lowercase.

I also think that iridescence-config.cmake is missing a call to

find_dependency(glm)

because client projects otherwise error.

Thanks for reporting the issue. I'll fix the first one by checking both glm_FOUND and GLM_FOUND. I'll update CMakeLists to resolve both soon.
