The old version would lead to error when Catch was installed
as a subproject. The file would be written to the subproject's
build directory and then would not be installed properly.
Create a namespaced Catch2::Catch target that is 'linkable' through
`target_link_libraries()` and export it so it is findable through
`find_package()`.
`find_package()` will find versions with the same major number and with
minor number >= requested.
This makes catch a lot easier to use in CMake-based projects. Whether it
is found using `find_package` or included in the client project as a
subdirectory, the client can include the catch headers per-target with
`target_include_directories(target PRIVATE Catch2::Catch).
Example usage:
cmake_minimum_required(VERSION 3.1)
# include Catch2 as subdirectory or installed package
# add_subdirectory(Catch2)
find_package(Catch2 VERSION 2.1.0 REQUIRED)
add_executable(tests tests/catch_main.cpp)
target_link_libraries(tests PRIVATE Catch2::Catch)
Also had to add new project to redirect CTest output, add
separate batch scripts for AppVeyor because it doesn't handle
multi-line batch scripts in yaml properly, and other helper
scripts.
* Every Linux build tracks coverage when running Debug mode
* OS X not supported yet (Future WIP)
* Our own unit tests, non-default reporters and Clara are ignored
- Added new compilers and OS X images
- Option to run SelfTest under Valgrind
- Merge "Debug" and "Release" configurations into one run
-- This saves apt setup and cmake download step per compiler, 60-90s
- Fix C++14 compilation under Clang 3.8 and up
to prevent inheritance of include directories that possibly lead to a clash.
A clash occurs when a folder is included, e.g. examples, that wants to use the single-include directory instead of the normal include directory as used by the SelfTest in the next higher level.
Also hides std::chrono, std::pair and std::chrono::* behind
new configuration macros, CATCH_CONFIG_ENABLE_*_STRINGMAKER
to avoid dragging in <utility>, <tuple> and <chrono> in common
path, unless requested.
Swept:
`-Wpadded` in some places (where it caused extra size, instead of just
saying "hey, we padded struct at the end to align, just as standard says")
`-Wweak-vtables` everywhere (Clang)
`-Wexit-time-destructors` everywhere (Clang)
`-Wmissing-noreturn` everywhere (Clang)
The last three are enabled for Clang compilation going forward.
Also enabled `-Wunreachable-code` for Clang and GCC
Note, this doesn't mean it will start passing, just that it will
run the approval tests properly
Some changes are needed before it passes, as the Windows output
somewhat differs.
