Sorry if this has come up before...
I'm attempting to compile OSG 2.5 and when I do the ./configure, I get:
CMake Error: Error in cmake code at

When I look in the cmake 2.4.6 directory, I don't see a file called
FindPkgConfig... However, if I look in CMAKE 2.6, I see such a file... The
readme for OSG says it needs 2.4.6 or newer.. Did this requirement change.
It seems that a change was made to CMakeLists.txt in early May which causes
this include to now be used.
This is a bug in OSG's build scripts.
Since OSG is now using PKG_CHECK_MODULES (which was introduced in CMake
2.4.7) someone should either:
1. Bump CMAKE_MINIMUM_REQUIRED() to 2.4.7 at the top of the root
CMakeLists.txt file to provide a more friendly warning for users that they
need a newer version, or
2. Add checks around the usage of PKG_CHECK_MODULES. People using the
older versions of CMake prior to 2.4.7 would not be able to link against the
new dependencies but they would still be able to configure and build without
error.
FIND_PACKAGE(PkgConfig)
IF(PKG_CONFIG_FOUND)
# use pkg_check_modules()
ENDIF(PKG_CONFIG_FOUND)
