# Sofa support in MML
#
# Note that only MML_SOFA_STABLE is currently/actively supported
#
# This file defines the following variables:
# - SOFA_SUPPORTED_VERSION the name of the currently supported Sofa stable version
# this is equal to the git tag
# - SOFA_BUILD_DIR To be set by the user to the Sofa build directory
# This is mandatory to have the Sofa support
#
# If Sofa support is enabled by the user by setting the build directory,
# the following variables are defined:
# - SOFA_SUPPORT Set to ON
# - SOFA_SOURCE_DIR The top-level directory of the Sofa source.
# Automatically extracted/hacked from the CMakeCache.txt in the
# build directory (${SOFA_BUILD_DIR})
# - SOFA_LIBS List of Sofa libraries to link against needed at link time
# - SOFA_LIB_DIR Directory where to find the compiled Sofa libraries
# - SOFA_INCLUDE_DIR Sofa include directories needed a compile time
#
# If Sofa support is enabled by the user by setting the build directory,
# the following flags needs to be defined at compilation time:
# -DSOFA_SUPPORT
# -DSOFA_PATH="${SOFA_BUILD_DIR}"
# -DSOFA_STABLE
# list of possibly supported sofa STABLE version
# Only stable version are supported in MML
set(SOFA_STABLE_V15_03 "sofa-v15.03")
# The currently supported Sofa version
# Only stable version are supported in MML
# To support a new version, add a new SOFA_STABLE_V... above and modify this
set(SOFA_SUPPORTED_VERSION ${SOFA_STABLE_V15_03})
# "find" SOFA (you need to have a SOFA_BUILD_DIR environment variable
# or to define it manually during configuration process)
set(SOFA_BUILD_DIR $ENV{SOFA_BUILD_DIR} CACHE PATH "Where to find SOFA (stable) ${SOFA_SUPPORTED_VERSION} build directory")

# # use Find SOFA script
# set(SOFA_BUILD_DIR ${SOFA_SOURCE_DIR})
# include(${SOFA_BUILD_DIR}/cmake/Modules/FindSOFA.cmake)
# list(APPEND CMAKE_MODULE_PATH "${SOFA_BUILD_DIR}/cmake/Modules")
# find_package(SOFA)
# # Check the FindSofa.cmake and "translate" all their variables here
# set(SOFA_INCLUDE_DIR ${SOFA_INCLUDE_DIRS})
# set(SOFA_LIBS ${SOFA_LIB_CORE}
# ${SOFA_LIB_HELPER}
# ${SOFA_LIB_DEFAULT_TYPE})
# For now, lets trick it!
# Problem with the current way Sofa uses cmake:
# - there is no install procedure
# - everything needed at MML compile-time (headers mainly) are to be found in the source directory
# - everything needed at MML link-time (lib mainly) are to be found in the build directory
# The hack to solve this consists in parsing the CMakeCache file (which is in the build directory toplevel)
# to automatically get the value the source directory (in the CMAKE_SOURCE_DIR variable)
# So here it is in two steps
# 1. Get the correct line from the CMakeCache file
file(STRINGS ${SOFA_BUILD_DIR}/CMakeCache.txt SOFA_SOURCE_DIR_LINE REGEX "^Sofa_SOURCE_DIR:STATIC=(.*)$")
# 2. Use a regex to extract the path from the line
string(REGEX REPLACE "^Sofa_SOURCE_DIR:STATIC=(.*)$" "\\1" SOFA_SOURCE_DIR "${SOFA_SOURCE_DIR_LINE}")
message("Detected Sofa ${MML_SOFA_STABLE} source directory is ${SOFA_SOURCE_DIR}")
# fill the list of needed libraries
# the only way to find the required lib is to hack the files generated by cmake:
# cd ${SOFA_BUILD_DIR}/applications/projects/runSofa
# cat CMakeFiles/runSofa.dir/link.txt | sed 's/\s/\n/g' | grep ../../../lib | sed "s+../../../lib/lib++g" | sed "s+.so++g"
# explained:
# - first sed to explode the one line into one word per line
# - first grep to get only the Sofa library
# - second sed to remove the ../../../lib/
# - third sed to remove the trailing .so
