[gmp] 6.3.0 Build on Windows could be great if it could identify patch levels

[twata1]

Is your feature request related to a problem? Please describe.

Thanks for providing the vcpkg.

Currently, gmp version is v6.3.0.
If I just use the library, I don't know if it is #0, #1 or #2.
v6.3.0#2 includes #42443 .
It is no longer easy to distinguish whether a library is built with cl.exe or with gcc.exe or others.

Proposed solution

Define something like __GNU_MP_VCPKG_VERSION_PATCH_LEVEL in gmp.h.

Describe alternatives you've considered

No response

Additional context

As stated in the INSTALL file of MPFR 4.2.1, if the MPFR-formatted output functions based on ISO-conforming printf() are to be used in gcc.exe, gmp may be compiled with CC="gcc -D__USE_MINGW_ANSI_STDIO".
If a module provided in an LL language such as Perl deals with its gmp, it may fail in the test case of its output functions if it is not known which one the library was compiled with.

You can see the specific version number through the vcpkg command:

C:\123\vcpkg>vcpkg.exe install gmp:x64-windows
Computing installation plan...
The following packages are already installed:
    gmp:[email protected]#2

C:\123\vcpkg>vcpkg.exe search gmp
glpk[gmp]                                 Use the GNU Multiple Precision Arithmetic Library
gmp                      6.3.0#2          The GNU Multiple Precision Arithmetic Library
gmp[fat]                                  Enable runtime selection of optimized low level routines

Thank you for your reply.

The following is an example of execution in my environment, but you can certainly see that it is vcpkg search gmp.

C:\utilities\vcpkg>vcpkg search gmp
glpk[gmp]                                 Use the GNU Multiple Precision Arithmetic Library
gmp                      6.3.0#2          The GNU Multiple Precision Arithmetic Library
gmp[fat]                                  Enable runtime selection of optimized low level routines

But if I use a previous version in another directory, I don't know what version it is (Version 6.3.0#2 should not have been released on 09/22/2024.).

You can use the vcpkg.exe list command to check the port version numbers you have already installed.

@Mengna-Li
Thank you again.

It is my understanding that in your opinion the vcpkg ... command will tell you the version of the installed library.
In fact, at the time I broke the vcpkg environment when I tried to update gmp.
Once I had almost emptied the c:\utilities\vcpkg folder and reintroduced it.
The results of vcpkg.exe list in my environment are as follows:

C:\utilities\vcpkg>vcpkg.exe list
