[Interest] Qt5.15 from source on centOS 7

[Alexander Carôt]

Hej Mike, Thiago and Chris,

in fact the configure process does not recognize the new installed 1.1.1 version (see extract of config.log):

loaded result for library config.qtbase_network.libraries.openssl
Trying source 0 (type openssl) of library openssl ...
$OPENSSL_LIBS is not set.
  => source produced no result.
Trying source 1 (type inline) of library openssl ...
  => source failed condition 'config.win32'.
Trying source 2 (type inline) of library openssl ...
  => source failed condition 'config.msvc'.
Trying source 3 (type inline) of library openssl ...
  => source failed condition 'config.android'.
Trying source 4 (type inline) of library openssl ...

Regarding Mike's email below I double checked and saw that all the required files are in place plus created the symbolic links in /usr/lib64/pkgconfig plus deleted the old 1.0.x-devel package.

Looks like there is a tiny last step to walk but I still wonder how to make it recognize / which variable to set etc.

Thanks

Alex
