CMake version specification doesn't work

[rutsky]

I'm using GLM version 0.9.8.1 from Debian package on 64-bit GNU/Linux (https://packages.debian.org/sid/libglm-dev).
When I'm trying to specify in my CMakeLists.txt minimal required GLM version:

find_package(glm 0.9.8 REQUIRED)

I get CMake error:

CMake Error at CMakeLists.txt:21 (find_package):
  Could not find a configuration file for package "glm" that is compatible
  with requested version "0.9.8".

  The following configuration files were considered but not accepted:

    /usr/lib/cmake/glm/glmConfig.cmake, version: unknown



*** cmake process exited with exit code 1.

Requirement without version specification works fine:

find_package(glm REQUIRED)

Could you be so kind and elaborate? What doesn't work?

Sorry, I see the problem. PR will follow shortly.

Seems like I named version file incorrectly - according to Package_Version_Files it should be glmConfigVersion.cmake not glmVersion.cmake.

See #573.
Once it is included in release you can use it with ExternalProject as follows:

externalproject_add(glm URL https://github.com/g-truc/glm/releases/download/<version>/glm-<version>.zip URL_MD5 <hash>)

Thanks @shaxbee for the quick resolution. Having a quick look I noticed this file name different but I haven't sue it matters.

@rutsky, it would be great if you could have a look to double check it's working just fine for you.

This is issue should be fixed in GLM 0.9.8 branch for GLM 0.9.8.3 release and in master branch.

Thanks,
Christophe

@shaxbee thanks for the quick fix!

@Groovounet I can confirm that renaming glmVersion.cmake to glmConfigVersion.cmake fixes the issue on my system.

Thanks! :)
