renderercommon is now used, which will appropriately use opengl1 when building static libraries, or compile both opengl1/opengl2 modules when building shared libraries
This removes coupling between the renderer and UI/client functions. An option USE_RENDERER_DLOPEN was added to specify whether a renderer module should be compiled and loaded, instead of integrating the renderer into the executable directly. This opens the door for a new renderer
Each target will produce a single binary having multiple architectures, instead of having a binary per architecture. The suffix for each binary will be `multiarch`. This makes it easier for the end-user to install and use. This also helps the transition between Intel and Apple Silicon hardware
Some distros install to lib64 instead of lib, respect the lib extension
otherwise some {f,c}game gets installed to lib64 and other libs get
installed to lib.
On Win32:
- Binaries and libraries will be installed by default in <PREFIX>/bin
- The prefix is set to `Program Files/openmohaa` by default
On Unix:
- Binaries and libraries will be installed by default in <PREFIX>/lib/openmohaa
- Shared data will be installed in <PREFIX>/share/applications, <PREFIX>/share/metainfo and <PREFIX>/share/icons
- The prefix is set to `/usr/local` by default
This removes the use of the DESTINATION parameter from install() command and instead rely on default values.
The shared build action file was modified to package installed files in a single folder
Add a .desktop file, this is used by application launchers in order to
find and execute applications, this should be installed to
`/usr/share/applications/org.openmoh.openmohaa.desktop`.
Add appstream metainfo, this provides metainfo that is used by Software
Centers for discoverability, this should be installed to
`/usr/share/metainfo/org.openmoh.openmohaa.metainfo.xml`.
This will open the door to getting OpenMoHAA packaged up by various
linux distros.
This fixes an issue where shared libraries would use functions from in the executable because they have the same name, which would cause memory corruption
