test cuda: import fmt in CUDA source code
Current test is only for Windows(cl.exe).
Need to test more with the other host compilers...
* Activate the test when `find_package(CUDA)` worked
* The test runs with C++14
Detailed comments in 'test/cuda-test'
test cuda: add more comment / macro check
* checks both `__NVCC__` and `__CUDACC__`
More comments for CMake and CUDA source file.
test cuda: <fmt/core.h> checks NVCC and CUDA
The header file checks 2 things.
* __NVCC__: if the compiler is from NVIDIA
* __CUDACC__: if the source code is CUDA(.cu) file
Since we can't sure all users prefer latest, Version for
`find_pacakge(CUDA)` is downgraded to 9.0.
This is the minimum version for C++14 in CUDA
* Fix conditional `char8_t` from `format.h` and fix `-Wunused-result` of [[no_discard]] begin() when in c++17
* Suppress `-Winconsistent-dllimport` when in clang-target-msvc
* Suppress warning _CRT_SECURE_NO_WARNINGS in MSVC and -Wdeprecated-declarations
Suppress warning _CRT_SECURE_NO_WARNINGS in MSVC and -Wdeprecated-declarations of POSIX functions in Clang target MSVC.
Those functions are used by gtest.
* Remove FMT_FUNC, mark FMT_API to export
* Add a _lot_ more warnings to FMT_PEDANTIC
Fix these warnings
* Add more compilers to CI
Fix (some) of the compiler errors with them
* Enable -Werror on CI
Increase warning level on MSVC when compiling with FMT_PEDANTIC
* Add VS 2013 and 2015 to Appveyor
* Fix Appveyor tests
Formatting
* Implement requested changes
Fix some of the MSVC warnings
Implement C++11 integer_sequence
* Reintroduce appveyor-build.py
* Remove ranges-test from tests
* Remove (some) explicit warning suppressions
Fix C++ standard setting in CI
* Remove (some) explicit warning suppressions
Fix C++ standard setting in CI
* Fix test builds with C++11
* Enable pedantic warnings on tests
* Fix warnings from edits to master
* Cleanups
* Add C++11 support to ranges.h
Re-enable ranges-test
Fix a Visual Studio error about function not returning a value in printf.h
Fix a bug in .travis.yml
The failure would happen when the main project was configured with
a compiler which is not the system default. The new configuration
was not forwarded to "ctest --build-and-test". This fixes it.
