* [vcpkg.cmake] modify to get in line with the audit See PR #16055 This also (attempts to) allow vcpkg.cmake to run with cmake 3.0; we had a VERSION_GREATER_EQUAL check, but that if keyword was added in cmake 3.7. * s/target_name/package_name in find_package * depend on z_vcpkg_function_arguments instead of a custom macro also, as a drive-by, switch to foreach(X IN LISTS ...) * split the utility macros/functions out additionally, move the options and settings to the top of the file * move more options and settings to the top * fix name of file * fix ras code comments * remove z_vcpkg_utilities due to export * add cmake_policy(PUSH|POP) * add VCPKG_INSTALLED_DIR input variable * add .cmakestamp to vcpkg_installed * fix osx ifs to use quotes also, remove spaces between if and (, to keep style consistent (mostly for ease of grepping...) * fix bug fixed by #16193 * move z_vcpkg_add_fatal_error up * fix RANGE for reals

# z_vcpkg_function_arguments
|
|
|
|
**Only for internal use in vcpkg helpers. Behavior and arguments will change without notice.**
|
|
Get a list of the arguments which were passed in.
|
|
Unlike `ARGV`, which is simply the arguments joined with `;`,
|
|
so that `(A B)` is not distinguishable from `("A;B")`,
|
|
this macro gives `"A;B"` for the first argument list,
|
|
and `"A\;B"` for the second.
|
|
|
|
```cmake
|
|
z_vcpkg_function_arguments(<out-var> [<N>])
|
|
```
|
|
|
|
`z_vcpkg_function_arguments` gets the arguments between `ARGV<N>` and the last argument.
|
|
`<N>` defaults to `0`, so that all arguments are taken.
|
|
|
|
## Example:
|
|
```cmake
|
|
function(foo_replacement)
|
|
z_vcpkg_function_arguments(ARGS)
|
|
foo(${ARGS})
|
|
...
|
|
endfunction()
|
|
```

|
|
set(z_vcpkg_function_arguments_FIRST_ARG 0)
