Minor cmake issues

[wjaskowski]

Got:

Make Error at /usr/share/cmake-3.2/Modules/FindPackageHandleStandardArgs.cmake:138 (message):
  Could NOT find JNI (missing: JAVA_AWT_LIBRARY JAVA_JVM_LIBRARY
  JAVA_INCLUDE_PATH JAVA_INCLUDE_PATH2 JAVA_AWT_INCLUDE_PATH)
Call Stack (most recent call first):
  /usr/share/cmake-3.2/Modules/FindPackageHandleStandardArgs.cmake:374 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/cmake-3.2/Modules/FindJNI.cmake:287 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:85 (find_package)

Solution:

export JAVA_HOME=/usr/lib/jvm/java-8-oracle

Got:

-- checking for module 'gtk+-2.0'
--   package 'gtk+-2.0' not found
-- Could NOT find OpenAL (missing:  OPENAL_LIBRARY OPENAL_INCLUDE_DIR) 
-- Could not find FMOD include files
-- Could NOT find SndFile (missing:  SNDFILE_LIBRARY SNDFILE_INCLUDE_DIR) 
-- Could NOT find MPG123 (missing:  MPG123_LIBRARIES MPG123_INCLUDE_DIR) 
-- Could NOT find FluidSynth (missing:  FLUIDSYNTH_LIBRARIES FLUIDSYNTH_INCLUDE_DIR) 

But cmake succeeded. So, is it a problem?

If it work it should not be a problem. Zdoom describes theses packages as optional so I guess now we know what they meant.

Yes - JAVA_HOME must be set. CMake will now show error message if it isn't.
All this packages are optional and used only for mp3 and 3d sound support.
