Adding additional components via Kconfig
Posted: Sun Nov 08, 2020 12:47 pm
I am writing a component where I want the possibility to enable advanced features that depend on other components (in this case lvgl).
The CMakeList.txt looks like this (simplified)
I can see the "LVGL enabled" output and the correct content of priv_requires on the console, however a build fails because it complains about missing the lvgl.h header file. The include is not present in the build.ninja for the appropriate target. However when I uncomment the line in the else clause then it works and the build.ninja gets generated correctly. Can someone tell me what I am doing wrong?
I am using esp-idf v4.1 and VisualGDB
The CMakeList.txt looks like this (simplified)
Code: Select all
if(CONFIG_USE_LVGL)
set(priv_requires driver freertos lvgl)
message("LVGL enabled")
else()
set(priv_requires driver freertos)
#The following works???
#set(priv_requires driver freertos lvgl)
message("LVGL disabled")
endif()
message("priv_requires: ${priv_requires}")
idf_component_register(SRCS "${srcs}"
INCLUDE_DIRS include
PRIV_INCLUDE_DIRS source
PRIV_REQUIRES "${priv_requires}")I am using esp-idf v4.1 and VisualGDB
