+By default cmake will build both shared and static libraries as well

+cmake variables: `BUILD_SHARED_LIBS`,`BUILD_STATIC_LIBS`,`BUILD_FORT_LIBS`.
+For example:
+```
+cmake  -DBUILD_SHARED_LIBS=OFF -BUILD_STATIC_LIBS=ON -DBUILD_FORT_LIBS=OFF -s ../parlib

+by using cmake-gui or using `cmake -LAH `.
