[digiKam-users] Compiling digikam and exiv2

[woenx]

Thank you Gilles,

I've been so far unable to compile it so digikam's bootstrap.linux script
detects it.

The steps I followed were: 

1) Download the last release of exiv2 (0.27.1) from github.
https://github.com/Exiv2/exiv2/releases/tag/0.27.1
2) Uncompress the tar.gz file, and copy the bootstrap-exiv2.linux.sh script
to the main exiv folder (where CMakeLists.txt is).
3) Run './bootstrap-exiv2.linux.sh'
4) Enter the build directory, and run 'cmake --build .'
5) 'sudo make install'
6) I update the PATH (as instructed in their github page): 'export
PATH="/usr/local/bin:$PATH" && export
LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"'

Exiv's 2 seems to compile without errors, and I can run the exiv2 command in
the terminal.

digikam at digikam-VirtualBox:~/digikam$ exiv2 --version
exiv2 0.27.99.0

However, when I try to compile digikam (the lastest version from github),
libexiv2 cannot be found:

https://pastebin.com/xQsfWwHb

Is libexiv2 a separate package from exiv2?

I am a bit lost at the moment, and I am not sure how to check if the
PKGConfig files are correctly created after compiling exiv2. These are the
files related to exiv2 I find using the locate command:
https://pastebin.com/TXTkAa3q

Any advise or guidance would be greatly appreciated!
