These variables get set to /usr/lib and /usr/include , which is totally wrong in a cross compilation
environment.
Changed to standard pkgconfig values consistent with most other ones.
string_view_metadata was introduced to make compiled format relocatable.
However, format string compilation is an optimization and therefore
adding overhead and extra complexity for relocation is undesirable.
In most cases the string will be either static or outlive compilation
and formatting and if it doesn't, it's possible to make compiled
representation relocatale by other means.
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
To avoid clang warning:
fmtlib/include/fmt/chrono.h:753:32: error: declaration shadows a field of 'formatter<duration<type-parameter-0-0, type-parameter-0-1>, type-parameter-0-2, void>' [-Werror,-Wshadow]
gcc-9 gives the following shadow warning:
```
In file included from /Users/libraries/ioss/src/fmt/ostream.h:12,
from /Users/libraries/ioss/src/Ioss_DatabaseIO.C:59:
/Users/libraries/ioss/src/fmt/format.h: In function 'void fmt::v6::internal::parse_format_string(fmt::v6::basic_string_view<Char>, Handler&&)':
/Users/libraries/ioss/src/fmt/format.h:2442:10: warning: declaration of 'struct fmt::v6::internal::parse_format_string(fmt::v6::basic_string_view<Char>, Handler&&)::writer' shadows a global declaration [-Wshadow]

/Users/libraries/ioss/src/fmt/format.h:1703:7: note: shadowed declaration is here
1703 | using writer = basic_writer<buffer_range<char>>;
| ^~~~~~
```
Since the `writer` struct is only used internally in the `parse_format_string` function, its name can be changed somewhat aribtrarily to avoid conflicts with names in an outer scope.
Note that this warning is also present in the 6.0.0 release.
