[gdal-dev] link error with MrSID and ECW

[Kai Pastor, DG0YT]

IMO you ask for trouble when you manually inject -DFRMT_mrsid=ON  into 
CFLAGS and CXXFLAGS. This is CMake input ("ON"!). Let the configuration 
do that for you. Did configuration successfully detect the dependency? 
Check the config logs.
