$ cat xlsxwriter.pc

Name: libxlsxwriter
Description: A C library for creating Excel XLSX files
Version: 4
Cflags: -I${includedir}
Libs: -L${libdir} -lxlsxwriter -lz

somehow this regex in CMakeLists.txt evaluates to 4:

string(REGEX MATCH "LXW_VERSION .*\"\(.*\)\".*" _ ${ver})

Thanks. I can confirm it happens on macOS as well. I'll take a look.

The greedy dot star strikes again.

The existing regex probably worked until the SOVERSION was added, which gave it an extra set of double quotes to match against. Anyway, I've pushed a fix to main that you can try.
