- probe only for system lib (i.e. only probe in prefix paths)
old code ended up not installing the json lib due to finding a copy
in the build folder if a reconfiguration was performed.
- build internal copy static and bundle in libopm-json.so
no reason to install this as a shared library. if it is updated
originating from opm, the entire parser library is updated anyways.
this is required to make the opm-core build succeed if ERT was build
with -DBUILD_SHARED_LIBS=OFF . (without it, I get errors like
/home/and/src/ert/devel/libert_util/src/thread_pool_posix.c:328: error: undefined reference to 'pthread_create'
it turns out that boost::regex does not work for the libstdc++ debug
mode. This patch should fix this for sufficiently new compilers.
Note that this requires the FindCXX11Features.cmake tests pulled in
from opm-core and an additional compiler flag...
this is required for regex-matching keywords. Once GCC 4.9 is the
minimum compiler version to be supported, this can be dropped in favor
of std::regex ...
While reformatting the parser-prereqs file I accidentally replaced
the feature search 'CXX11Features' with 'CXX10Features'. This
commit fixes that blunder.
The benchmark library uses Boost::iostreams to do decompression. Since
we only scan for the Boost dependency once, this submodule is added to
all of the projects in order to have a coherent dependency on Boost.
This commit makes a few adjustments to the white-space of file
'opm-parser-prereqs.cmake' to honour the conventions of the other
*-prereqs.cmake files within the OPM project's module suites.
No functional changes.
Instead of guessing the suffix or subdir of the build directory,
we now simply compare PROJECT_{BINARY,SOURCE]_DIR to detect it.
By this e.g. opm-core/opm-parallel is a possible build directory, too.
If opm-parser_ROOT is given, this should point to a build tree. The
only way to extract the corresponding source directory is to parse
the build cache located there.
Although CMake prefers the uppercase variant variables, and the
find_package_handle_standard_args will convert to them for us, the
part that parses REQUIRED and QUIET arguments to find_package still
only uses the package name verbatim (sic).
It doesn't really matter here because "cjson" is only letters, but as
a general rule we define the uppercase variant ourselves so that CMake
doesn't use its own (bizarre) case rules, and then set the lower case
explicitly afterwards.
CMake will do some uppercasing of its own (defining OPM-PARSER_FOUND)
so it works best if we specify the correct uppercase version and sets
the lowercase afterwards.
The CMake script is run in the source tree. We assume a certain
directory layout and that the cjson is available in a sibling
directory of this project. Thus, we can pick up a build tree without
having the library installed.
The library will end up in the opm/json library in a build tree; we
want to be able to point the CJSON_ROOT variable to the root of the
build tree and have it pick up the libraries from there.
