AEC_INCLUDE_DIRS is undefined in src/CMakeLists.txt

[DusanJovic-NOAA]

Include directories for libaec are specified by using variable AEC_INCLUDE_DIRS:

./src/CMakeLists.txt:147:  target_include_directories(${lib_name}_objlib PRIVATE "${AEC_INCLUDE_DIRS}")
./src/CMakeLists.txt:151:    target_include_directories(${lib_name}_shared PRIVATE "${AEC_INCLUDE_DIRS}")
./src/CMakeLists.txt:155:    target_include_directories(${lib_name}_static PRIVATE "${AEC_INCLUDE_DIRS}")

but AEC_INCLUDE_DIRS is undefined, probably a typo (AEC_INCLUDE_DIR is defined). Find module sets LIBAEC_INCLUDE_DIRS and LIBAEC_LIBRARIES and these two variables should be used. There is no need to introduce local variables with the same values, for example:

diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt

Is AEC working now? If so, this issue can be closed.
