Compile error on knx_facade.h when importing library in third party PIO project

[PaoloTK]

I would like to use this library to add KNX compatibility to WLED, which is a software to drive LEDs that runs on ESP. However when I try to include <knx.h> on my class I get an error:

expected type-specifier before ')' token

The error occurs on line 80 col 74 of knx_facade.h, on the B init:

https://github.com/thelsing/knx/blob/150f3fc24b363e5c35ca474eb8332ee82a262d0d/src/knx_facade.h#L80

I haven't started using the library yet, the include alone causes the compile error.

Here's my platformio.ini:

[env:esp32_knx]
extends = esp32dev
platform = espressif32
framework = arduino
board = esp32dev
lib_deps = ${esp32.lib_deps}
  https://github.com/thelsing/knx
upload_speed = 921600
lib_ldf_mode = deep+
build_flags = ${common.build_flags} ${esp32.build_flags}
  -D USERMOD_KNX
  -D WLED_DEBUG
  -D MASK_VERSION=0x07B0
  -Wno-unknown-pragmas

Any idea if this is an issue on my side, WLED side or the library?

Without seeing any code it's hard to say. Can you try to build the knx-demo example first? According to github action CI it compiles fine for esp32. If you have the code somewhere I can take a look at it.
