Actions CI failing for cmake

Actions CI failing for cmake for last 4 days

Last successful run

First failed run

-- Found PkgConfig: /usr/bin/pkg-config (found version "0.29.1") 
CMake Error at CMakeLists.txt:348 (find_package):
  Could not find a package configuration file provided by "Leptonica"
-- Configuring incomplete, errors occurred!
See also "/home/runner/work/tesseract/tesseract/build/CMakeFiles/CMakeOutput.log".
  (requested version 1.74) with any of the following names:

    LeptonicaConfig.cmake
    leptonica-config.cmake

  Add the installation prefix of "Leptonica" to CMAKE_PREFIX_PATH or set
  "Leptonica_DIR" to a directory containing one of the above files.  If
  "Leptonica" provides a separate development package or SDK, be sure it has
  been installed.


Error: Process completed with exit code 1.

AFAIK the latest leptonica (1.82) should be used as there are needed fixes for cmake

I solved this. But it is failing on Mac and I can not test it why...

Thanks @zdenop

On macos it is failing with the following while building the basicapitest
Failing Run on MacOS

I tried to see whether it is possible to DISABLE curl while building tesseract but that didn't work either.

Actions CI environment for macos has curl preinstalled, hence -lcurl needed to be added for macos for the build of basicapitest.

See https://github.com/Shreeshrii/tesseract/actions/runs/1298540885 for working run.

PR #3589 fixes this.

[zdenop]

I have a feeling ;-) that generating tesseract.pc is not perfect. I suggest to use/prefer cmake function in cmake chain. Unfortunately I have not time to dig in it.

[Shreeshrii]

Actions CI for cmake is working now. Successful log.

I'll leave it for cmake experts to fix. I am closing this issue as CI is working now.
