57 * file format loader. The loader is be excluded from the
58 * build in this case. 'XX' stands for the most common file

60 * ASSIMP_BUILD_NO_X_IMPORTER disables the X loader.

62 * If you're unsure about that, take a look at the implementation of the
63 * import plugin you wish to disable. You'll find the right define in the
64 * first lines of the corresponding unit.
65 *
66 * Other (mixed) configuration switches are listed here:
67 * ASSIMP_BUILD_NO_COMPRESSED_X
68 * - Disable support for compressed X files (zip)
69 * ASSIMP_BUILD_NO_COMPRESSED_BLEND
70 * - Disable support for compressed Blender files (zip)
71 * ASSIMP_BUILD_NO_COMPRESSED_IFC
72 * - Disable support for IFCZIP files (unzip)
