build error

[whyuu]

Context
shiftmediaproject\libilbc\rtc_base\checks.h(57,10): fatal error C1083: “absl/meta/type_traits.h”: No such file or directory ..\common_audio\signal_processing\dot_product_with_scale.cc)
shiftmediaproject\libilbc\rtc_base\checks.h(57,10): fatal error C1083: “absl/meta/type_traits.h”: No such file or directory ( ..\rtc_base\checks.cc)

Expected Behavior
No additional operations are required to compile successfully
Steps to Reproduce
open resolution
select release dll
build
Your Environment
win10 + vs2019

Possible Fix
I solved it this way, but not sure if this is appropriate

1. Copy two files config.h versin.h from the old version and put them in the smp directory
2. Download the abseil-cpp project, copy the absl directory to the libilbc root directory
