Changeset 2616 for code/branches/buildsystem2/cmake/LibraryConfig.cmake

Timestamp:

Jan 29, 2009, 10:55:29 PM (16 years ago)

Author:

Message:

• Split FindOggVorbis.cmake in two. Having them in one file doesn't make sense, we can group it somewhere else.
• Updated all find scripts
• Removed all standard paths (like /usr /usr/local, etc.) because they're already searched by CMake anyway
• Several workarounds for certain libraries when using the find script in the CMake module path.

File:

• code/branches/buildsystem2/cmake/LibraryConfig.cmake (modified) (2 diffs)

+##### CEGUI #####
+# We make use of the CEGUI script module called CEGUILua.
+# However there is a small issue with that: We use Tolua, a C++ binding
+# generator ourselves. And we also have to use our bindings in the same
+# lua state is CEGUILua's. Unfortunately this implies that both lua runtime
+# version are equal or else you get segmentation faults.
+# In order to match the Lua versions we decided to ship CEGUILua in our
+# repository, mainly because there is no way to determine which version of
+# Lua CEGUILua was linked against (you'd have to specify yourself) and secondly
+# because we can then choose the Lua version. Future plans might involve only
+# accepting Lua 5.1.
