Toolchain fails to build -- "Could NOT find OpenSSL ... (missing: OPENSSL_CRYPTO_LIBRARY OPENSSL_INCLUDE_DIR)"

[HUNT3Rdotme]

Running on an updated Ubuntu 22.04.3 via Windows 11 22H2 and WSL2, starting fresh, I get this trying to run Meta/serenity.sh rebuild-toolchain:

loading initial cache file /home/hunter/serenity/Toolchain/Build/cmake/Bootstrap.cmk/InitialCacheFlags.cmake
-- Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY OPENSSL_INCLUDE_DIR)
CMake Error at Utilities/cmcurl/CMakeLists.txt:608 (message):
  Could not find OpenSSL.  Install an OpenSSL development package or
  configure CMake with -DCMAKE_USE_OPENSSL=OFF to build without OpenSSL.


-- Configuring incomplete, errors occurred!

Error when bootstrapping CMake:

Some Googling -- or in my case, DuckDuckGoing -- led me to a similar issue on the openssl_cmake repo, and I am in no way technically inclined to figure anything out in there beyond "try installing a package, maybe it's missing", which I already did anyway. Here's the link to my comment in particular, which also links to this issue.

If you build or download CMake >= 3.25 yourself and put it in your PATH, the toolchain will not try to build its own CMake binary. On Ubuntu, you can get that from either apt.kitware.com as a deb or as a snap from https://snapcraft.io/cmake.

Not sure what's up with the cmake build error, but you might need to install libopenssl-dev ?

Just to re-iterate: the build error you are receiving is from building cmake, not from building gcc, clang, binutils, or the code from this repo :)

Whoops, forgot to bring that up beforehand! Thanks!

you might need to install libopenssl-dev ?

E: Unable to locate package libopenssl-dev

...so yeah that's out the window. 😅

On Ubuntu, you can get [Cmake >= 3.25] from ... apt.kitware.com as a deb....

Awesome! I'll try that now and report the results back.

Update: Kitware repo worked! Closing issue.
