+    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:
