In commit f91e4863bc1382 we fixed an issue where LZ4_LIBS could be
overwritten in some situations. But on systems where lz4 is installed on
the system but is lacking pkg-config information, the linker will not know
about the lz4 library when completing the build.
This fixes the issue by
ACK. Makes sense, got tested on our problem child (Debian 8) already,
and I added more tests of my own (Ubuntu 14.04 with "too old lz4 library",
FreeBSD with 1.8.0, Gentoo with "no lz4 library") and everything worked
nicely. thanks.
Your patch has been applied to the master and release/2.4
Older LZ4 library versions used a version number > 100 and not the
current x.y.z versioning scheme. This results in version 122 being
numberically higher than the check we have liblz4 > 1.7.1. And
since that old version (122) does not have the LZ4_compress_default(),
the building explodes later
