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
