I was able to make it to work:
find_program(MKOCTFILE_EXECUTABLE mkoctfile)
if(NOT MKOCTFILE_EXECUTABLE)
message(SEND_ERROR "Failed to find mkoctfile, is it in your $PATH?")
endif()
## Compile the octfile
set(OCT_CXXFLAGS "-O2 -Wall -Wextra -std=c++0x")
set(ENV{CXXFLAGS} ${OCT_CXXFLAGS})
set(OCT_FILE "${PROJECT_BINARY_DIR}/multidecksieve.oct")
set(OCT_SRC ${CMAKE_CURRENT_SOURCE_DIR}/multidecksieve.cpp)
set(CPPLIB_DIR ${CMAKE_CURRENT_SOURCE_DIR}/../core/build)
set(CPPLIB_INCLUDE_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../core")
find_library(CPPLIB_SIEVE_LIBRARY NAMES sieve PATHS ${CPPLIB_DIR})
if ("${CPPLIB_SIEVE_LIBRARY}" STREQUAL "CPPLIB_SIEVE_LIBRARY-NOTFOUND")
message(FATAL_ERROR "One of the libraries wasn't found!")
endif ()
set(CPPLIB_LIBRARIES "${CMAKE_CURRENT_SOURCE_DIR}/../core/build")
set(CPPLIB_HINT_INCLUDE_DIR ${CPPLIB_DIR})
set(DEPENDENCIES ${OCT_SRC} ${CPPLIB_SIEVE_LIBRARY})
add_custom_command(
OUTPUT ${OCT_FILE}
DEPENDS ${DEPENDENCIES}
COMMAND ${MKOCTFILE_EXECUTABLE}
ARGS ${OCT_SRC}
ARGS -I${CPPLIB_INCLUDE_DIR} -L${CPPLIB_DIR} -lsieve
COMMENT "Generating ${OCT_FILE}"
VERBATIM)
add_custom_target(multidecksieve ALL
DEPENDS ${OCT_FILE})
It compiles fine, but when I run the created file (in GNU Octave) I
get an error message saying the library libsieve.so is not found
although it exists on the provided path. What is the problem here?
Thanks for any answer
Reza
