--with-textcat: configure error?

[Felipe Gasper]

Hello,

        With Dovecot 2.3.18 on AlmaLinux 8 I’m trying this:

LIBEXTTEXTCAT_LIBS="-L/usr/lib64 -lexttextcat" ./configure --with-textcat

… which gives me:

checking for special_textcat_Init in -lexttextcat... no
checking for special_textcat_Init in -ltextcat... no
configure: error: Can't build with textcat support: libtextcat or libexttextcat 
not found

I do have:

> ls -la /usr/lib64 | grep textcat
lrwxrwxrwx   1 root root       26 Oct 12  2019 libexttextcat-2.0.so.0 -> 
libexttextcat-2.0.so.0.0.0
-rwxr-xr-x   1 root root    22128 Oct 12  2019 libexttextcat-2.0.so.0.0.0

        Is there some way of knowing what command it’s actually running that 
makes it say “libtextcat or libexttextcat not found”?

        Thank you!

cheers,
