I've done so investigating, looking into adding the txp directory into
the include paths, and by enabling the verbose makefile output I got
the following output:

[106%] Building CXX object
src/osgPlugins/txp/CMakeFiles/osgdb_txp.dir/TileMapper.o
/usr/bin/c++   -Dosgdb_txp_EXPORTS   -g -fPIC
-I/home/robert/OpenSceneGraph/include
-I/home/robert/OpenSceneGraph/src/osgPlugins/txp/.   -o
src/osgPlugins/txp/CMakeFiles/osgdb_txp.dir/TileMapper.o -c
/home/robert/OpenSceneGraph/src/osgPlugins/txp/TileMapper.cpp


Note the -I/home/robert/OpenSceneGraph/src/osgPlugins/txp/. entry
which probably goes a long way to explaining why Linux compiles just
fine.  To enable the verbose makefile output  run ccmake . in the root
OpenSceneGraph directory and then press 't' to toggle on the advanced
options, then scroll down to the CMAKE_VERBOSE_MAKEFILE entry and
toggle this from OFF to ON.  Then press 'c' then 'g' to configure and
generate the fine makefiles.

This should give you some direction on what might be up.

Robert.
