+Subject: [PATCH] CMakeLists.txt: fix paths when FTDIPP is set
+
+Use the same project name (i.e. libftdi1 and not libftdipp1) when FTDIPP
+is enabled as suggested by Aurelien Jarno in
+http://developer.intra2net.com/mailarchive/html/libftdi/2020/msg00044.html
+
+Without this change, the libftdi1.pc config file defines the include
+path as /usr/local/include/libftdipp1 while the ftdi.h file is actually
+installed in /usr/local/include/libftdi1
+
+This is an issue for example for libsigrok which will fail on:
+
+In file included from src/hardware/asix-sigma/protocol.c:27:
+src/hardware/asix-sigma/protocol.h:28:10: fatal error: ftdi.h: No such file or directory
+   28 | #include <ftdi.h>
+      |          ^~~~~~~~
+
+Fixes:
