build a lib with specified version

[alimai]

I try to build a lib with specified version, and find a suggestion as following in #11768 :

1. Use command .\vcpkg x-history qt5
2. Get the commit id of the version you need.
3. Use command git reset
4. Rebuild qt5.

I do a test with the zlib(The latest version of zlib in vcpkg is 1.2.11-6),
Vcpkg still build the latest version of module when I following the suggestion of @timautry timautry.

1. git reset 18b029a
2. .\vcpkg x-history zlib
   version date vcpkg commit
   1.2.11-5 2019-06-15 18b029a
   1.2.11-3 2018-08-30 ab54bfa
   1.2.11-2 2017-09-23 67e876c
   1.2.11-1 2017-09-09 26516fe
   1.2.11 2017-01-17 0d50c67
   1.2.10 2017-01-04 6a220ed
   1.2.8 2016-11-08 1808d46
   [note: It seems the current version should be 1.2.11-5 now.]
3. .\vcpkg install zlib

4. .\vcpkg list
   zlib:x64-windows 1.2.11-6 A compression library

The installed version is still 1.2.11-6, is there any thing wrong?

Confirmed, but I think this is just a display issue.

Hi, it seem not that.
if you test the boost module, you will find that the vcpkg download the tar.gz file with latest version from github.

git reset 18b029a probably requires --hard to reset the working tree instead of leaving it untouched ;)

Oh, do you mean the buildtree?
I test it with a new vcpkg, no lib has been installed before, so there don't have any of the following folder: buildtrees,downloads,installed,packages

And I try reset it with --hard option,
After that, the vcpkg told me to run 'bootstrap-vcpkg.bat',
Then I got many many errors.

@ras0219 @ras0219-msft Could you take a look?

Thanks.

@alimai the correct command to run is probably:

$ git checkout <copied commit> -- ports/<port-name>

This will check out only the specified port from the tree. You can also do something like:

$ mkdir pinned-ports
$ git checkout <copied commit> -- ports/<port-name>
$ mv ports/<port-name> pinned-ports
$ git checkout HEAD -- ports

and then proceed to use vcpkg with the additional flag --overlay-ports=./pinned-ports :)

Thanks. It works now.
