# vim: et ts=4 sts=4 sw=4 tw=0
ENH: Provide range for non-warned cmake versions Allow configuring without cmake policy developer warnings for a range of cmake versions. This prevents the need to explicitly enumerate every new policy for each new cmake version. === Moved setting of the CMAKE_CXX_STANDARD to before the project() directive.
2018-12-12 17:02:42 +01:00
# ==== Define cmake build policies that affect compilation and linkage default behaviors
#
# Set the JSONCPP_NEWEST_VALIDATED_POLICIES_VERSION string to the newest cmake version
# policies that provide successful builds. By setting JSONCPP_NEWEST_VALIDATED_POLICIES_VERSION
# to a value greater than the oldest policies, all policies between
# JSONCPP_OLDEST_VALIDATED_POLICIES_VERSION and CMAKE_VERSION (used for this build)
# are set to their NEW behaivor, thereby suppressing policy warnings related to policies
# between the JSONCPP_OLDEST_VALIDATED_POLICIES_VERSION and CMAKE_VERSION.
#
# CMake versions greater than the JSONCPP_NEWEST_VALIDATED_POLICIES_VERSION policies will
# continue to generate policy warnings "CMake Warning (dev)...Policy CMP0XXX is not set:"
#
Update minimum CMake version requirement

- New CMake based build system. Based in part on contribution from Igor Okulist and Damien Buhl (Patch #14). Added support for running tests and building with DLL on Windows. - added missing JSON_API - Visual Studio DLL: suppressed warning "C4251: <data member>: <type> needs to have dll-interface to be used by..." via pragma push/pop in json-cpp headers. - New header json/version.h now contains version number macros (JSONCPP_VERSION_MAJOR, JSONCPP_VERSION_MINOR, JSONCPP_VERSION_PATCH and JSONCPP_VERSION_HEXA). While this header is generated by CMake, it is committed to ease build with alternate build system (CMake only update the file when it changes avoid issues with VCS).

ENH: Refactor and enhance the CI testing infrastructure 1) Improve travis build script for use outside travis. Allow the script used for CI builds to also be used locally in a similar manner to the CI use of the scrips 2) Add ctest compatible testing and CDASH support Report testing and building results to https://my.cdash.org/index.php?project=jsoncpp NOTE: The new ctest infrastructure is not yet robust on winodws Do no yet enable the new features for running test with ctest on windows platform. The previous behaviors are maintainted, but enhance test reporting from windows is not yet supported. 3) Add a cmake coverage testing option Ensure that cmake builds on linux are tested. Ensure that code coverage is reported. 4) Move conditional environment checking into the matrix Avoid multiple places where conditional logic is used to change compiler behavior. As more test environments are created fromt the travis.yml matrix, all settings should be obvious from that one location. 5) Tests with known regressions from the jsonchecker are suppressed Tests that are known to pass with jsoncpp more lenient syntax enforcement are exluded from tests in test/runjsontests.py

- New CMake based build system. Based in part on contribution from Igor Okulist and Damien Buhl (Patch #14). Added support for running tests and building with DLL on Windows. - added missing JSON_API - Visual Studio DLL: suppressed warning "C4251: <data member>: <type> needs to have dll-interface to be used by..." via pragma push/pop in json-cpp headers. - New header json/version.h now contains version number macros (JSONCPP_VERSION_MAJOR, JSONCPP_VERSION_MINOR, JSONCPP_VERSION_PATCH and JSONCPP_VERSION_HEXA). While this header is generated by CMake, it is committed to ease build with alternate build system (CMake only update the file when it changes avoid issues with VCS).
