Compilation on Linux x64

[theo-dep]

Hi,

I am trying to understand the vcpkg repository example but I am facing this issue when I run vcpkg install in the beson-ptr example:

.../vcpkg/buildtrees/beison/src/b7a414bcb0-d477a732e3.clean/src/beison.cpp: In static member function ‘static beison::Value beison::Value::number(double)’:
.../vcpkg/buildtrees/beison/src/b7a414bcb0-d477a732e3.clean/src/beison.cpp:252:22: error: ‘isfinite’ was not declared in this scope
  252 |                 if (!isfinite(d)) std::abort();
      |                      ^~~~~~~~

      |                                                                        ^~~~~~~~

The fix is to include cmath and to replace isfinite by std::isfinite

@theo-dep I'm having the same issue. Followed the tutorial found here https://learn.microsoft.com/en-us/vcpkg/consume/git-registries. Here is my relevant system information.

$ uname -a

Linux ubuntu-linux-22-04-02-desktop 6.5.0-35-generic #35~22.04.1-Ubuntu x86_64 x86_64 x86_64 GNU/Linux

and the relevant command used with cmake,

cmake -B build -S . \
-DCMAKE_TOOLCHAIN_FILE=$VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake \
-DCMAKE_C_COMPILER=$(which gcc) \
-DCMAKE_CXX_COMPILER=$(which g++)

along with the compiler versions,

$ gcc --version

If this repo has gone stale, the associated tutorial should be removed or modified to show it working. I will open up a proxy issue in https://github.com/microsoft/vcpkg-docs/issues, and hopefully we'll get a PR accepted, or doc change.
