 ### CMake build options
 The cmake-build-environment provides options to configure the build. The following options can be used:
-- **BUILD_SHARED_LIBS ( default ON )**: Generation of shared libs ( dll for windows, so for Linux ). Set this to OFF to get a static lib.
-- **BUILD_FRAMEWORK ( default OFF, MacOnly)**: Build package as Mac OS X Framework bundle
-- **ASSIMP_DOUBLE_PRECISION( default OFF )**: All data will be stored as double values.
-- **ASSIMP_OPT_BUILD_PACKAGES ( default OFF)**: Set to ON to generate CPack configuration files and packaging targets
-- **ASSIMP_ANDROID_JNIIOSYSTEM ( default OFF )**: Android JNI IOSystem support is active
-- **ASSIMP_NO_EXPORT ( default OFF )**: Disable Assimp's export functionality
-- **ASSIMP_BUILD_ZLIB ( default OFF )**: Build your own zlib
-- **ASSIMP_BUILD_ASSIMP_TOOLS ( default ON )**: If the supplementary tools for Assimp are built in addition to the library.
-- **ASSIMP_BUILD_SAMPLES ( default OFF )**: If the official samples are built as well (needs Glut).
-- **ASSIMP_BUILD_TESTS ( default ON )**: If the test suite for Assimp is built in addition to the library.
-- **ASSIMP_COVERALLS ( default OFF )**: Enable this to measure test coverage.
-- **ASSIMP_ERROR_MAX( default OFF)**: Enable all warnings.
-- **ASSIMP_WERROR( default OFF )**: Treat warnings as errors.
-- **ASSIMP_ASAN ( default OFF )**: Enable AddressSanitizer.
-- **ASSIMP_UBSAN ( default OFF )**: Enable Undefined Behavior sanitizer.
-- **SYSTEM_IRRXML ( default OFF )**: Use system installed Irrlicht/IrrXML library.
-- **BUILD_DOCS ( default OFF )**: Build documentation using Doxygen.
-- **INJECT_DEBUG_POSTFIX( default ON )**: Inject debug postfix in .a/.so lib names
-- **IGNORE_GIT_HASH ( default OFF )**: Don't call git to get the hash.
-- **ASSIMP_INSTALL_PDB ( default ON )**: Install MSVC debug files.
