Can not compile UIMA C++ examples in Mac OS X

There is a few issues in base.mak that make it difficult to build annotators in Mac OS X.
Users must fix not only the path to APR includes as stated in the README, but also for ICU and XERCES-C. The same for the libraries.
The BIN_LINKFLAGS is not set, but required to build it successfully.
Also, at least for Sierra, the default CC compiler will not work. Tried to change compiler to g++5 and could compile.
The includes that comes with the binary distribution are not compatible with MAC OS X, so it should not be used.
