Title: CMake not finding Freetype error (on Windows)
Post by: Bloodwurm on 26 February 2012, 18:09:07

I just resynched the master branch and went through the complete setup phase for devs.
I did get the Freetype error again (just like the first time I set myself up).

I tried recopying the freetype stuff everywhere, even installed the full GNUWin32 freetype package but to no avail.

In the end, I had to manually add a FREETYPE_INCLUDE_DIRS and set it to this path: C:/Projets/glestae/source/gae-deps/include/freetype2 (would obviously need to be adapted to your personal install). It then stopped complaining about not finding it and I was able to complete the process and compile and run gae.

I was tempted to modify the install steps directly but i wonder if some of the principal devs should look at it a bit more? I think there is an issue with the cmake file itself (as if the FREETYPE_INLUDE_DIRS should already be defined in the script when used but isn't) but I don't know much about that tech so...

Where and what is the exact error?

Freetype includes are already set in CMakeLists.txt:

Code: [Select]

set(ENV{FREETYPE_DIR} ${GAE_WINDEPS})
find_package(Freetype REQUIRED)

This is what CMake spits out:

Perhaps there's a CMake version difference. I have 2.8.2.

In my FindFreetype.cmake, FIND_PACKAGE_HANDLE_STANDARD_ARGS is at line 92 instead of 83 and before that it has code to set FREETYPE_INCLUDE_DIRS. This could be missing in your version?

Code: [Select]

# set the user variables
IF(FREETYPE_INCLUDE_DIR_ft2build AND FREETYPE_INCLUDE_DIR_freetype2)
  SET(FREETYPE_INCLUDE_DIRS "${FREETYPE_INCLUDE_DIR_ft2build};${FREETYPE_INCLUDE_DIR_freetype2}")
ENDIF(FREETYPE_INCLUDE_DIR_ft2build AND FREETYPE_INCLUDE_DIR_freetype2)
SET(FREETYPE_LIBRARIES "${FREETYPE_LIBRARY}")

Yeah, they changed the find module a bit and broke the hints (cmake 2.8.7). It can't find ft2build.h that way. It's now set directly as a workaround. Hopefully that fixes the problem. I have no windows system to test it on, so feedback is welcome.

[Maybe we should move this to another thread  :) ]
Yeah ok we surely dont have the same version considering I downloaded the most recent but by looking into my findfreetype.cmake in Cmake 2.8 this is what I have which seems to pretty much fit what you are talking about so...:
BTW, manually adding the var in cmake (like for GAE_WINDEPS) makes it work, but will it induce other problems? (like not using the proper version of something? it is compiling and linking fine....)

PS: I pasted everything from the file besides the top comments.

The FIND_PATHs are slightly different in my version. Setting the dirs manually seems to work anyway.
