#266 cmake build for lodo appears to ignore CMAKE_INCLUDE_PATH

[Andrew Symington]

Since I use Macports, I have the following two environment variables set in ~/.profile:

export CMAKE_INCLUDE_PATH=/opt/local/include
export CMAKE_LIBRARY_PATH=/opt/local/lib

However, when I try to build player from SVN the lodo module fails to find a GSL include, resulting in the following error:

...
[ 97%] Built target lodo

GSL is definitely installed. Here is some info from pkg-config

andrew-symingtons-macbook-pro-15:stage-svn asymingt$ pkg-config --cflags gsl
-I/opt/local/include
andrew-symingtons-macbook-pro-15:stage-svn asymingt$ pkg-config --libs gsl
-L/opt/local/lib -lgsl -lgslcblas -lm
andrew-symingtons-macbook-pro-15:stage-svn asymingt$ pkg-config --modversion gsl

I suspect this might have to do with the cmake build files. I ran cmake with verbosity and inserted -I/opt/local/include into the two failed build steps. Everything compiled successfully thereafter. Since I am unfamiliar with cmake, I am unable to post an updated build script or patch.

I checked out latest SVN version and manually deleted CMakeCache.txt. After this change everything worked as expected.
