I think I found the problem. Where is
APR_INCLUDE_DIR
set from
APR_INCLUDE_DIR_INT?? All I find is:
EXEC_PROGRAM(${APR_CONFIG} ARGS "--includedir"
OUTPUT_VARIABLE
APR_INCLUDE_DIR_INT)
which works to set APR_INCLUDE_DIR_INT, but I can't
find anywhere that there is a:
SET(APR_INCLUDE_DIR ${APR_INCLUDE_DIR_INT})
I believe cmake generates the variable when the pkg config test is performed. cmake
generates many internal variables.
