complex situation: Re: [Cmake] how to find STATIC library, ignore DYNAMIC library

[William A. Hoffman]

You could try something like this.

1. Find the HDF static library with FIND_LIBRARY
2. Copy the static library into a directory in your build tree
with 

EXEC_PROGRAM( ${CMAKE_COMMAND} -E copy_if_different ${HDF_LIB} ${PROJECT_BINARY_DIR}/HDFStaticLib)

3. Add the link directory for HDFStaticLib first with
LINK_DIRECTORIES(${PROJECT_BINARY_DIR}/HDFStaticLib)

4. Add the library like this:
TARGET_LINK_LIBRARIES(foo ${PROJECT_BINARY_DIR}/HDFStaticLib/HDF)
