Building ftgl backend with current tip

[Thomas Weber]

Hi, 

can anybody lend me a hand on how to run configure for the ftgl backend?

Running  
        $ ./configure --include=/usr/include/freetype2/
gives me the following in config.log:

configure:10988: gcc -o conftest -g -O2 -I/usr/include/freetype2    conftest.c 
-lfreetype -lz -lhdf5 -lz -lm  >&5
configure:10991: $? = 0
configure:10997: ./conftest
configure:11000: $? = 0
configure:11020: result: yes
configure:11109: checking FTGL/ftgl.h usability
configure:11126: g++ -c -g -O2   conftest.cpp >&5
In file included from /usr/include/FTGL/ftgl.h:32,
                 from conftest.cpp:77:
/usr/include/ft2build.h:56:38: error: freetype/config/ftheader.h: No such file 
or directory

freetype-config is in /usr/bin/
ftheader.h is in /usr/include/freetype2/freetype/config/

Thanks
        Thomas
