Conversation
In the past, the only way to build openfastlib as a shared library was to set -DBUILD_SHARED=ON. This library is now always built as shared but many users still set BUILD_SHARED which causes all module libraries to be created as shared which means that all must be dynamically loaded at run time. This commit changes the CMakeLists.txt files to build all module libs as STATIC regardless of BUILD_SHARED. This means that all module libraries will be statically linked into openfast, openfastlib and FAST.Farm which should improve performance and reduce complexity

Feature or improvement description
This PR changes the CMakeLists.txt files in each module so that the module libraries are built as STATIC even if CMake is configured with
-DBUILD_SHARED_LIBS=ON. Interface libraries (C-Bindings) andopenfastlibare always built as shared libraries so this change will not affect downstream users. This option is part of CMake: BUILD_SHARED_LIBSImpacted areas of the software
CMakeLists.txt files of all modules
Additional supporting information
This change arose from a problem installing WEIS which built OpenFAST with
-DBUILD_SHARED_LIBS=ON. At one point, the only way to buildopenfastlibas a shared library was to set-DBUILD_SHARED_LIBS=ON. This library is currently always built as shared but many users still setBUILD_SHARED_LIBS=ONwhich causes all module libraries to be created as shared libraries so they are dynamically loaded at run time. This commit changes the CMakeLists.txt files to build all module libs asSTATICregardless of howBUILD_SHARED_LIBSis set. As a result, all module libraries will be statically linked intoopenfast,openfastlibandFAST.Farmwhich should improve performance and reduce complexity. This also prevents a problem with building the Simulink MEX file which wouldn't work ifBUILD_SHARED_LIBS=ON.
